← Nature & AnimalsWhich outcome reduces nutrient availability when transpiration decreases in plants?
A)Lowered cohesion-tension mechanism pull strength✓
B)Decreased root uptake efficiency limits
C)Increased enzymatic breakdown near xylem
D)Elevated osmotic potential traps minerals
💡 Explanation
Lower transpiration reduces water flow via the cohesion-tension mechanism, thereby limiting upward nutrient transport, because xylem sap flow decreases. Therefore, fewer nutrients reach leaves, rather than increased root uptake efficiency resulting in excess minerals in specific tissues.
